The World Science Fiction Society Constitution allows, but does not require, a Worldcon held 50, 75, or 100 years after a Worldcon at which no Hugo Awards were presented to present Retrospective Hugo Awards for works that would have been eligible for that year’s Hugo Awards if they had been held. (Once Retro Hugos have been presented for a given year, no future Worldcon may present Retro Hugos for that year.) The 1951 Worldcon did not present Hugo Awards. The Millennium Philcon elected to present Retro Hugo Awards for works first published in 1950 that would have been eligible for the 1951 Hugo Awards, had there been Awards presented in 1951.
